Using Tiefenbach gravity shunting systems (Tiefenbach Microcomputer Controlled), marshalling/classification yards with gravity humps can be automated in a low-cost manner.
The track control system is constructed using our proven points control systems in a modular design which are networked to a central gravity shunting computer
(COMPEX® system) via 2-wire serial data buses.
Controlling the gravity shunting system is carried out by personnel on the spot. The track routes can be entered via a track control panel with memory and display for the splitting-up list (EBA approved), or alternatively, over a control box with control buttons and built-in PC Visualization system.
The points control system also allows points to be set locally by the shunting personnel.
Using further proven Tiefenbach system components from the area of high-performance marshalling/classification yard systems (previously Hauhinco Eisenbahntechnik), the splitting-up and combining operations can be extensively automated so that even with small and medium-sized gravity shunting systems, the whole operation can be handled with a high degree of logic and at a low cost. The components available for this include:

• Wagon hauling equipment for automatically clearing and closing-up on marshalling tracks
   

• Track retarder controls using the COMPEX system
   

• Microcomputer controlled piston retarder sets for defined braking on marshalling tracks
